TO ALL WHOM IT MAY GONCERN:

Be it known that I, THOMAS NEWELL, of Oskaloosa, Mahaska county, Iowa, have invented certain new and useful improvements in Stove-Pipe Thimbles and do hereby declare that the following is a full, clear, and exact description of the same, reference being had to the accompanying drawings, and the letters of reference marked thereon, making apart of this specification.

In the annexed drawings, A represents a quadrilateral-Shaped block of stone, having a shoulder made in the same near the lower portion, as seen-at a. At the bottom of this block of stone is cut a ring, B, of a suitable size and thickness. This ring, B, is an annular dove-tailed groove, so constructed as to receive and secure the'plastering, which comes iiush against the side and bottom of said ring, and forming a neat finish. Through the centre of said block is made a circular opening, (as seen at D, g. 3,) to allow the stove pipeJ or the products of combustion, to pass through. C represents a ring at the top of the block, and is used only when the thimble is for partitions or doors, but is omitted whenever the flue is built upon the top of the block.

The object of my invention is, constructing a stove-pipe thimble that can be used for iioors, partitions, or to build a iiue upon it, to prevent the many res that occur from imperfect chimneys, ues, &c. This thimble is cut of one piece ofstone, and is placed between the joists, E, fig. 3, in the oor, and resting upon cleats, j', by the shoulders, a a. d represents the lath, while F is the floor above, with a lid, Gr, to cover the opening, D, in the summer time, when the thimble is notI used. The ordinary sized thimbles are cut about fourteen inches square and eight inches in thickness, and the cleats f fbeing about two inches wide, and there are about two inches extending below the cleats and `joist, so that when the lath, d, and Plastering are added, they are even with the bottom of the thimble, as heretofore described. After the stove thimble is placed between the joists, the brick ue is built directly upon it, so that there Ais no wood nearer than the joists. By the dimensions before described it will be seen that the thimble is three inches thick every way, and issecure against fires, which is the great object of the device.

Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent, as a new article of manufacture, is-

The quadrlateral-shaped stone A, with two shoulders, a a, for resting it upon cleats between the joists, and annular dove-tailed grooved ring B, constructed, as described, of one piece of stone, as and for the purposes set forth.

As evidence that I claim the foregoing, I have hereunto set my hand in the presence of two witnesses.

THOS. N EWELL.
